A microstrip patch antenna is designed to serve as both the radiator and the harmonic tuner of a power amplifier in a high-efficiency transmitter operating in the Ku-band. A circular-sector patch is used in conjunction with a double tuning stub in order to synthesize the optimal complex input impedance as a load for the power amplifier at the operating frequency. A compact filter is further inserted in the line that feeds the patch in order to achieve a complete impedance mismatch at the third harmonic frequency. Numerical full-wave simulations are reported for both the input impedance and the radiation pattern of the antenna, which confirm the effectiveness of the proposed design.

Abstract
A microstrip patch antenna is designed to serve as both the radiator and the harmonic tuner of a power amplifier in a high-efficiency transmitter operating in the Ku-band. A circular-sector patch is used in conjunction with a double tuning stub in order to synthesize the optimal complex input impedance as a load for the power amplifier at the operating frequency. A compact filter is further inserted in the line that feeds the patch in order to achieve a complete impedance mismatch at the third harmonic frequency. Numerical full-wave simulations are reported for both the input impedance and the radiation pattern of the antenna, which confirm the effectiveness of the proposed design.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
